Cannot see the images from Forward Mails

[lumanthony]

I have started to use Thunderbird. Recently I have faced one problem. I will demonstrate in a case scenario. I have received an email which has embedded images inside from the person A. I can see the images up to this moment. Then, I forward that email to the person B. The person B (the recipient) cannot see the images while I could not see the images for that Forward mail as well. I have tried many methods which I could find from online forum sources. Methods are like checking Allow Remote Content and Option tab> Advanced tab> Config Editor> etc. These are the links I found out for methods:
- http://forums.mozillazine.org/viewtopic ... 882#635882
- http://kb.mozillazine.org/Privacy_basics_(Thunderbird)
- http://kb.mozillazine.org/Images_in_mes ... not_appear
Please suggest me what did I miss out? Or is there any particular method to solve this case?

Does the recipient receive a HTML message?

The reason I ask is if my account is configured to compose messages as plain text and I forward a HTML message, it gets converted to plain text (thus dropping the images) unless I hold down the Shift key when selecting forward. Holding down the shift key when composing / replying / forwarding temporarily toggles the "compose messages in HTML" format setting in tools -> account settings -> account_name -> composition & addressing.
